Savi Technology, a Lockheed Martin company, today announced availability of their active RFID tage with Satellite Communications. Savi’s hybrid ST-694 GlobalTag provides continuous monitoring of assets most anytime and anywhere. The typical RFID read range for is 100 meters (328 feet), but the ST-694 GlobalTag can send a RFID signal and switch to satellite as local RFID readers loose contact.

The ST-694 also includes the SX1, a tag unveiled one year ago by Orbit One, a division of Numerex. The SX1 comes with a lithium battery, an internal motion sensor and an integrated GPS chipset, that communicates with Globalstar’s low Earth orbit (LEO) satellites.

The tag is programmed to activate several times per day, then send its GPS-determined location information (latitude and longitude) to the nearest LEO satellite. Whether operating as an active RFID tag or as a satellite tag, the ST-694 transmits its unique ID number.

The GlobalTag tracking technology, co-developed with Numerex, is available now for pilot field operations. It provides continuous in-transit visibility of shipments and mobile supply chain assets, such as transport vehicles, container shipments or large and valuable equipment.

The Savi hybrid ST-694 GlobalTag will conform to the DASH7 Alliance standard, a consortium of leading RFID industry players, that is developing extensions to the ISO 18000-7 standard, the standard for real-time locating systems that employ active tags operating at 433 MHz.

Numerex’s satellite products support firefighting, hurricane relief operations, cargo tracking and defense logistics.
